No, you've got your fantasy in my sci-fi!
There's a lot of talk lately about the resurgence of the old-school or the old school renaissance in RPGs and a call to return back to the roots of science fantasy. In fact some are calling for an escalation of these efforts (which I whole-heartedly embrace BTW). Apparently some people are squeamish about mixing the two, barring a few one-off exceptions. Which, to be honest, is understandable. Especially if you're trying to create a world where technology can't come in and trump your magic system or where an omnipotent race of aliens can easily annihilate your meticulously crafted medieval analogue world. For some, it was less of an issue, but most seem to be more comfortable keeping sci-fi and fantasy separate.
It occurred to me however that if you started with a sci-fi universe and sprinkled in some magic or low-tech, then people don't seem to mind. Mysticism and lasers seemed like two things too good to pass up.
Case in point:
...or so we thought, before 1999. But isn't it funny how (essentially working backwards in a sense) it's easier to think of a sci-fi world in the broad strokes of fantasy, than to try and upgrade an ancient world into a larger universe.
Food for thought I guess. Thoughts?
